Working with Circular Linked Lists in Python

Linked lists are fundamental data structures, but standard singly linked lists have limitations when it comes to representing cyclical data. Understanding how to connect the tail node back to the head unlocks powerful ways to model repeating processes and circular buffers. In this text-based course, you will transition from standard linear lists to circular linked lists using clean, modern Python. You will learn how to design node structures, handle edge cases during traversal, and implement core insertion and deletion algorithms with confidence. What you'll learn: - Understand the core differences between standard and circular linked lists - Implement a robust circular linked list class in Python using modern type hints - Traverse circular structures safely without getting stuck in infinite loops - Insert and delete nodes at the head, tail, and specific positions - Analyze the time and space complexity of circular list operations - Apply circular lists to solve real-world problems like round-robin scheduling You will start with the fundamental terminology and concepts of node-based structures before moving step-by-step through manual pointer manipulation. Through written explanations and clear code examples, you will build a fully functional circular linked list from scratch. This course is designed for beginner programmers and computer science students who have a basic grasp of Python and want to deepen their understanding of custom data structures.
